To J. D. Hooker 16 March 
Down Bromley Kent
My dear Hooker
I have had a note from J. Gray of Brit. Mus: asking for information about my system of publication.1 As it wd be a long story to tell him, I have said, that you would in a few days send him, the bundle of papers, which I sent you, & I asked him to return them to you.— I hope this will not inconvenience you.— I received from London (as I had occasion to send there) your infusorial specimens for Ehrenberg—I am astonished that I have not yet heard from him.— Your specimens anyhow shall be carefully preserved—I fear they are rather too bulky to go to Berlin, & I understand, that merest scraps are sufficient.— Any part, which I find I cannot send, shall be returned to you.
Ever yours | C. Darwin
